[U-Boot] [PATCH v2] OMAP3: BeagleBoard: add xM rev B to ID table

[Jason Kridner]

From: Koen Kooi <koen at dominion.thruhere.net>

Patch was updated by Jason Kridner <jkridner at beagleboard.org>:
* Use tabs to match style of other board revisions
* Only include board revisions that exist
* Default to the same configuration as the latest revision, but
  without setting 'beaglerev'
---
v2 Changes
  * Updated with feedback from http://patchwork.ozlabs.org/patch/71995/
  * Removed setting of mpurate based on board revision
  * Set mpurate to auto in default environment variables
